Hi Thanks to Jeremy for his response... I have been able to generate the factors and generate mlogit data using his code: mldata-mlogit.data(mydata, varying=NULL, choice=pitch_type_1, shape=wide) my mlogit data looks like: dependent_var,A variable,B Var,chid,alt FALSE,110,19,1,0

Hi All, I am attempting to build a Multinomial Logit model with dummy variables of the following form: Dependent Variable : 0-8 Discrete Choices Dummy Variable 1: 965 dummy varsgh...@student.monash.edu.augh@gp1.com Dummy Variable 2: 805 dummy vars The data set I am using has the dummy columns

If you are just looking to collapse the dummy variables into two factor variables, the following will work. ## Generate some example data set.seed(1234) n - 100 # Generate outcome outcome - rbinom(n, 3, 0.5) colnames(exposures) - paste(V, seq(1:10), sep = ) #Generate dummy variables for A and B
